36.5 Old Method for Registering C Modules.

** Auto-loading of compiled-code modules is deprecated.

Guile used to be able to automatically find and link a shared
library to satisfy requests for a module. For example, the module
`(foo bar)' could be implemented by placing a shared library named
"foo/libbar.so" (or with a different extension) in a directory on the
load path of Guile.

This has been found to be too tricky, and is no longer supported. The
shared libraries are now called "extensions". You should now write a
small Scheme file that calls `load-extension' to load the shared
library and initialize it explicitely.

The shared libraries themselves should be installed in the usual
places for shared libraries, with names like "libguile-foo-bar".
